Durchflussrate: The main pump of the PC200 – 8 hydraulic system has a maximum flow rate of 439 l/min. Der 708 – 2L – 00490 pump is designed to meet this flow requirement to ensure the normal operation of the excavator's hydraulic components.
Druck: The working pressure of the hydraulic system of the Komatsu PC200 – 8 varies according to different working conditions. The maximum pressure of the main hydraulic system is generally 37.3 MPA, and the control hydraulic system is 3.2 MPA. Der 708 – 2L – 00490 pump needs to work stably within this pressure range.
Structural Characteristics: It is likely to be a variable – Verschiebung axial – Kolbenpumpe. The axial – piston pump has the advantages of high efficiency and good variable – displacement performance, which can meet the requirements of different working conditions of the excavator. The pump body is made of high – strength alloy steel or cast iron, which has good wear – resistance and corrosion – Widerstand. The internal moving parts, such as pistons and swash plates, are made of wear – resistant materials to ensure a long service life.
